There's always someone who thinks they've found the Holy Grail
Maxima uses ester synthetic, which of the three types of synthetic oils is the most expensive and the best performing, It has the highest affinity for 'hot spots' in the engine, can get the hottest and maintain it's lubricating quality, it has the quickest performance at cooling down the hot surfaces in comes in contact with. Maxima doesn't 'make' ester synthetics, they have to buy the stocks and then formulate their own product from there just like all the companies do with their Group 4 and whatever the third and cheapest synthetic stock is.
It is an outstanding product and no truck oil that just happens to work good enough that the engine runs okay is anywhere close to it. Doug
